Kay Frierson is one of the protagonists in "The Great Mouse Detective 2: The Rise To Return". He is the younger brother of Norman Frierson, the grandson of Franklin and Esther Frierson, the son of Jeremiah and the late Phyllis Frierson, the nephew of Art and Diane Frierson and Byron and Melinda Doneeta, and the younger cousin of Kamaria and Rolf Frierson and Scotty Doneeta.
He first appeared in "The Great Mouse Detective" (with a non-speaking role) as one of the guests in Queen Mousetoria's Diamond Jubilee, who looked upon Jemediah Fieldson, who was berated by Ratigan because Fieldson is disabled.
He also has a crush on a preschool-aged girl mouse - Alana Chambers.
